Insert the spoon tire iron in between the metal rim and rubber tire.

Once inserted, tilt the tool back toward the middle of the wheel to loosen the rubber tire from the metal rim. The edge of the rubber tire should now be above the metal rim.

Insert the flathead screwdriver under the rubber tire to keep the edge in place and then remove the spoon tire iron and re-insert it between the metal rim and rubber tire a couple of inches away from where you first inserted it.

Repeat this process until the rubber tire comes off of the metal rim.
